Introduction Valproic acid (VPA, Valproate) is an eight-branch fatty acid and varies from other antiepileptic drugs. VPA use might lead to mild to severe hepatotoxicity. The aim of this study was to investigate valproic acid impact on liver transaminases at the beginning of VPA treatment and after three and six months of it. Materials and Methods This study was designed as a cross sectional pro...

Travelers returning from the tropics with fever remain a diagnostic challenge. Fever and chills suggest malaria, but may be present in dengue, chikungunya and influenza, and splenomegaly favors malaria or typhoid fever. In terms of laboratory tests, leukopenia suggests dengue fever, chikungunya fever or influenza. Atypical lymphocytes are present in malaria, dengue fever, chikungunya fever and ...

During the last decade the use of ω-transaminases has been identified as a very powerful method for the preparation of optically pure amines from the corresponding ketones. Their immense potential for the preparation of chiral amines, together with their ease of use in combination with existing biocatalytic methods, have made these biocatalysts a competitor to any chemical methodology for (asym...

Transaminases were first shown to be present in plant tissues by the early experiments of Virtanen and Laine (12), Albaum and Cohen (1), and Rautanen (9). In a later and more comprehensive paper Leonard and Burris (5) demonstrated transaminase activity in stem, leaf, and root tissues of numerous plant species. Wilson et al. (16) and Stumpf (11) further indicated the participation of plant enzym...

.ilthough there is ample evidence for the existence of many different transaminases, the lack of progress in the separation of more individually specific transaminases has been lamented by reviewers for a number of years. Transaminations involving glycine or glyoxylate have been studied extensively in crude preparations of animal (1, 2), plants (3), and microorganisms (4), as well as with purif...
